@florent, I had to do the same for Xen Orchestra Community Edition. In my case, config.toml already contained the [authentication] section, so adding a separate config.tokenValidity.toml file did not work.

Instead, I had to modify the existing config.toml located at /opt/xo/xo-server.

In my opinion, it is best to keep defaultTokenValidity set to 30 days as a fallback in case no value is specified. You can then simply increase maxTokenValidity to the duration you prefer.

[authentication]
defaultTokenValidity = '30 days'
# default value of 0.5 years
# comment out and increase to 5 years
#maxTokenValidity = ' 0.5 year'
maxTokenValidity = '5 year'

@olivierlambert is it already known in which update/release this problem will be solved?

@bleader I've done exactly the same on my ThinkSystem SR665 V3, BMC Version
3.20 (Build ID: KAX334O), UEFI Version 4.20 (Build ID: KAE120J), LXPM Version 4.12 (Build ID: GNL114G) and it worked;

I first checked the current system temperatures and fan speeds (configured at fix RPM);

@LennertvdBerg Lenovo didn't want to provide any support. However, they just published a new UEFI/BIOS. Not sure if this is going to fix things;

@RIX_IT I've dropped today a ticket as well, hoping them to realise it would be beneficial for all parties if they could help solving this.

@ThierryEscande Has anyone made any progress on this? @Riven you got contact details at Lenovo for contacting regarding this?

@stormi I’ll be back on Wednesday (just short holiday now), I’ll try your advice and see how it works

@stormi I thought it’s convenient to have all in one as it’s easy for installation. But I can check this options as well. So you recommend to extract the iso to a separate USB drive and load drivers from there?

@olivierlambert would there be a way after GRUB to walk step by step through the boot and see where it goes wrong?

@stormi Hi, some help is welcome Still haven’t found a solutions.

@ThierryEscande I've updated to Xen 4.17 and it seems the upgrade went fine:

However, the issues with the fan speeds and missing memory temperature readings still persist.

@ThierryEscande I'm experiencing difficulties with installing the kernel-alt package on my system. Currently, I am using XCP-ng version 8.3.0-beta2. It appears that there might be a problem with updategrub.py. Any guidance on how to resolve this would be greatly appreciated.

I've update xcp-ng.repo and this is my output of yum --enablerepo=xcp-ng-tescande install kernel-alt:

@olivierlambert Thanks.

@ThierryEscande . When I do lsmod | grep ipmiI get the following results

ipmi_si                65536  0 
ipmi_devintf           20480  0 
ipmi_msghandler        61440  2 ipmi_devintf,ipmi_si

So, I created the file with vi /etc/modprobe.d/blacklist-ipmi.conf and added the following:

blacklist ipmi_si
blacklist ipmi_devintf
blacklist ipmi_msghandler

I saved the file and rebooted the system using shutdown -r now. However, I still don't see the memory temperatures in Xclarity, and the server's fans are still running at over 13,000 RPM. The system is running XCP-NG 8.3 beta 2 with kernel 4.19.0+1.

@stormi could you maybe advise what I'm doing wrong?

@Danp, UPDATED: I tried booting with an alternate kernel in XCP-NG 8.2.1 and XCP-NG 8.3 beta 2, but it didn't load the Mellanox ConnectX-6 Lx 10/25GbE drivers.

Yes, I've read the documentation about creating a custom ISO and have detailed my procedure above. The only part I'm unsure about is this:
"you need to add new RPMs not just replace existing ones, they need to be pulled by another existing RPM as dependencies. If there's none suitable, you can add the dependency to the xcp-ng-deps RPM."
I couldn’t realize or understand this step.

I'm fairly new to XCP-NG and would like to build a custom ISO for XCP-NG where I can add an additional RPM for a Mellanox ConnectX-6 Lx 10/25GbE SFP28. The problem is that I don't have other NICs installed and I can't install XCP-NG 8.2.1 because it detects during installation that there's no NIC in the system. I can install XCP-NG 8.3 beta 2 as the drivers are included there. So, I would like to include the drivers for the Mellanox in the ISO so that during installation the process will automatically detect it and I can run the installation.

In xcp-ng-8.3.0-beta2, there's an additional mellanox-mlnxen-5.4_1.0.3.0-4.xcpng8.3.x86_64.rpm in the Packages/ directory. In xcp-ng-8.2.1-20231130, there is no mellanox-mlnxen*.rpm at all. I found two Mellanox RPMs at Koji;

• mellanox-mlnxen-alt-5.4_1.0.3.0-1.xcpng8.2.x86_64.rpm (https://koji.xcp-ng.org/buildinfo?buildID=2620)
• mellanox-mlnxen-alt-5.9_0.5.5.0-1.1.xcpng8.2.x86_64.rpm (https://koji.xcp-ng.org/buildinfo?buildID=2868)

I tried following the instructions for ISO modification mentioned in the XCP-NG ISO modification documentation

First, I extracted the ISO using the following commands:

mkdir tmpmountdir/
mount -o loop filename.iso tmpmountdir/ # as root
cp -a tmpmountdir/. iso
umount tmpmountdir/ # as root
chmod a+w iso/ -R

Then, I used wget to download the RPMs into the Packages/ directory. After this, I updated the repodata/ using the following command (remember to install createrepo-c first):"

sudo apt install createrepo-c
rm repodata/ -rf
createrepo_c . -o .

Finally, I built the ISO using the instructions given in the XCP-NG documentation:

#OUTPUT=/path/to/destination/iso/file # change me
OUTPUT=/home/xcp-ng/new_iso/xcp-ng-8.2.1-20231130-mod.iso
VERSION=8.2 # change me
genisoimage -o $OUTPUT -v -r -J --joliet-long -V "XCP-ng $VERSION" -c boot/isolinux/boot.cat -b boot/isolinux/isolinux.bin \
            -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e boot/efiboot.img -no-emul-boot .
isohybrid --uefi $OUTPUT

However, when I use this ISO, the Mellanox ConnectX-6 Lx drivers do not load during installation.

Also, I have seen on the Nvidia website that new drivers for the ConnectX-6 Lx are available for Citrix XenServer Host 8.2 in version mlnx-en-23.10-2.1.3.1-xenserver8.2-x86_64.

So my questions are:

• What am I doing wrong with building the ISO and including the RPMs?
• Is it possible to include the mlnx-en-23.10-2.1.3.1-xenserver8.2-x86_64 for XCP-NG 8.2?
• What steps do I need to take, and how?

@rmaclachlan Thanks. I'm also unsure how we can determine what in the OS is causing this issue. Are there other installations or modifications we could try to help isolate the problem, such as another Linux distribution with the same kernel, to see if it's a kernel-related issue? @gduperrey or @olivierlambert any suggestions how we can help the team with identifying this?

@olivierlambert can you help us with providing the module for the xen kernel, which @Gheppy is talking about?

@Gheppy I've just reinstalled xcp-ng-8.3.0-beta2 after my Ubuntu experiment and installed lm_sensors. The output is indeed:

Driver `to-be-written':
  * ISA bus, address 0xcc0
    Chip `IPMI BMC KCS' (confidence: 8)

Note: there is no driver for IPMI BMC KCS yet.
Check http://www.lm-sensors.org/wiki/Devices for updates.

No modules to load, skipping modules configuration.

Unloading i2c-dev... OK
Unloading cpuid... OK

The complete output is:

What will be the solution for this?
